Description
Technical field
The present invention relates to power transformation material property testing equipment technical fields, are a kind of power transformation material bending fatigue testers.
Background technique
Porcelain insulator is the important equipment of substation, plays the important function of electric insulation and mechanical support.In strong electromagnetic
Under the effect of the combined factors such as environment, long-term mechanical load and bad weather condition, the electromechanical properties of porcelain insulator will be remarkably decreased,
In addition product quality problems that may be present, are easy to cause fracture accident, and the quality problems of product are mainly porcelain insulator
The intensity (mainly bending strength and torsional strength) of existing defects (such as crackle) or porcelain insulator is inadequate.So national standard
Define in " insulator test method ": porcelain and glass insulator must carry out mechanical robustness testing, these mechanical tests include:
The tests such as stretching, compression, bending and torsion.The various machines that these mechanical test concentrated expressions insulator is born in substation
Whether tool intensity requirement meets the requirements additionally by processing qualities such as these test overall inspections porcelain piece production, mucilage bindings.
The equipment of high-voltage pillar porcelain insulator support includes disconnecting switch, bus, lead etc., entirely by lead, bus
And in the stress system that is connected with insulator of equipment, the bending resistance of insulator, torsional strength is paid attention to, the area Dan Feng it is long-term
Support insulator low-cycle fatigue damage caused by strong wind lacks more and more, so the flexural fatigue of research and assessment porcelain insulator is strong
Degree is just particularly important.
The bus fitting of electric substation fitting plays the role of fixed, support, connection bus, the mechanical load that can bear
Lotus matches with the high-voltage strut insulator requirement installed, the T-type fitting for especially playing lead to connect with pipe mother, in downlead
Under the action of power, biggish bending load will be born, in addition the flexible fitting of pipe mother, is subjected to bending load, also subject to torsion
Load, especially substation are located at strong wind area, pipe parent phase caused by lower lead is acted on due to continual strong wind connect fitting will bear it is larger
Bending, torsional fatigue load.Northwest China strong wind area in recent years, the gold of Duo Gechao, ultra-high voltage transformer station generator tube parent phase even
Has fracture accident, tracing it to its cause is that these fitting part bending resistance anti-twisting properties are insufficient, so in these installations before use, right
It is bent accordingly, fatigue test caused by torsion test and wind load is very necessary.
The porcelain insulator and fitting of substation stretch, compression test mixes suitable fixture on universal testing machine
It can be completed, but insulator and fitting is curved, torsional test, especially repeated bend test cannot achieve.Do not have same currently
Power transformation material (insulator and fitting) conventional curved, torsional test is realized on testing machine, and can be carried out the test dress of repeated bend test
It sets, to cannot achieve the Performance Evaluation to Substation Insulator and fitting.
